Overlapping Roller Shades
Two or more shades share two rolls in a single mount with each roll controlled independantly. Various alternating widths of shade material may be arranged on the pair of rollers which will overlap very closely. Individual shades can not exceed a width of 8½ feet.
For example, we can have three shades: two on the back roll flanking a third that overlaps them on the front role. The two in the back operate together while the middle shade moves by itself.
The key benefit to overlapping roller shades is the elimination of spaces between shading material in side by side installations. If the desired material can not be used to span the window in a continuous roll either because of pattern or weight, this approach still allows its use.
Shades can be manual chain, battery or motorized with ceiling or wall mounts.
